XP Wireless Network problem - been trying to fix this for days

[Bilbo]

I am hoping someone can give me some help here.

I have a 3-computer network. All are using Windows XP SP2. Simple
File Sharing is enabled on all.

Computer 1 is a laptop connected via ethernet cable to a D-Link DI-524
wireless router. This router is connected to a cable modem.
Computer 2 is a desktop, connected to the network via a wireless card
Computer 3 is a laptop, connected to the network using a PCMCIA wifi
card.

I set up shares on drives on all 3 computers.

Computer 1 can "see" both of the others, and can access the shared
folders on them.
Computer 2 can "see" 1 and 3, but when I try to access them, I get an
error saying I don't have permission to do so.
Computer 3 can't even "see" the other 2. When I click on "view
workgroup computers," I get an error message saying the workgroup is
inacessible and I don't have permission to do so."

All 3 can access the internet.

I used the Windows network setup, and still have problems. I am at my
wits end.

Any help greatly appreciated.

1) Disable firewall on computers and check again.
2) Some routers have wireless isolation thing where it disables file
sharing check if it is turned off.

Bilbo,

check http://winhlp.com/wxnet.htm and fill in the form. That
should yield the relevant solutions.

Firewalls were already disabled.
No such setting on the router. When I was running Win2K on all
computers, file sharing worked fine.
